(iii) all the relative extreme point(s) and point(s) of inflexion of f. WebDec 14, 2024 · Increasing on an interval (whether open or closed or mixed) means for any two points x, y in the interval so that x < y then it must follow that f ( x) ≤ f ( y). This seems to be the most accepted definition. So f is decreasing on ( 0, e] and decreasing on [ e, ∞). And increasing at x = e simply is not a meaningful concept.

WebApr 25, 2024 · The usual tool for deciding if f is increasing on an interval I is to calculate f' (x) = 2x. We use the theorem: if f is differentiable on an open interval J and if f' (x) > 0 for all x in J, then f is increasing on J . Okay, let's apply this to f (x) = x^2.
